Embodiment 1

[0018] A method for decolorizing an astragalus polysaccharide solution, comprising the following processing steps:

[0019] A. Transfer the macroporous weak base anion exchange resin to the resin column; wash the resin with alcohol at a flow rate of 90ml / h until the outflow of alcohol appears clear and not turbid in water, and set aside;

[0020] B. The resin is alternately treated twice with 1NHCl and 1NNaOH, and ends with 1NHCl treatment;

[0021] C. Wash the residual HCl in the resin column with deionized water to be close to neutral, and set aside; make the astragalus polysaccharide solution pass through the resin column at a flow rate of 100ml / h;

[0022] D. Collect the outflowing natural astragalus polysaccharide solution; vacuum concentrate, pulverize and sieve to obtain the product.

Embodiment 2

[0024] A method for decolorizing an astragalus polysaccharide solution, comprising the following processing steps:

[0025] A. Transfer the macroporous weak base anion exchange resin to the resin column; wash the resin with alcohol at a flow rate of 105ml / h, until the outflow of alcohol appears clear and not turbid in water, and set aside;

[0026] B. The resin is treated alternately with 1NHCl and 1NNaOH for 3 times, and the treatment ends with 1NHCl;

[0027] C. Wash the residual HCl in the resin column with deionized water to be close to neutral, and set aside; make the astragalus polysaccharide solution pass through the resin column at a flow rate of 110ml / h;

[0028] D. Collect the outflowing natural astragalus polysaccharide solution; vacuum concentrate, pulverize and sieve to obtain the product.

Embodiment 3

[0030] A method for decolorizing an astragalus polysaccharide solution, comprising the following processing steps:

[0031] A. Transfer the macroporous weak base anion exchange resin to the resin column; wash the resin with alcohol at a flow rate of 97.5ml / h, until the outflow of alcohol appears clear and not turbid in water, and set aside;

[0032] B. The resin is alternately treated twice with 1NHCl and 1NNaOH, and ends with 1NHCl treatment;

[0033] C. Wash the residual HCl in the resin column with deionized water to be close to neutral, and set aside; make the astragalus polysaccharide solution pass through the resin column at a flow rate of 105ml / h;

[0034] D. Collect the outflowing natural astragalus polysaccharide solution; vacuum concentrate, pulverize and sieve to obtain the product.

Abstract

The invention relates to a decolorization method of an astragalus polysaccharide solution, and belongs to the technical field of ion exchange resin. A pigment in natural astragalus polysaccharide is removed by adopting macroporous weak-base ion exchange resin chromatography, so that the astragalus polysaccharide can be completely applied to preparation of cosmetics. The method has the advantages of simplicity for operation, low cost, good pigment removal effect and the like.

Description

technical field [0001] The invention relates to a decolorization method, more specifically, the invention relates to a decolorization method of astragalus polysaccharide solution, which belongs to the technical field of ion exchange resins. Background technique [0002] Astragalus polysaccharide is a water-soluble heteropolysaccharide obtained by extracting, concentrating, and purifying the dried root of Astragalus mongolica or Astragalus membranaceus, a leguminous plant. It is light yellow, fine powder, uniform and free of impurities, and has hygroscopicity. Astragalus polysaccharides are composed of hexuronic acid, glucose, fructose, rhamnose, arabinose, galacturonic acid and glucuronic acid. Radiation, anti-stress, anti-oxidation and other effects. [0003] When extracting natural astragalus polysaccharides to prepare various health care products or cosmetic additives, it is often required that the polysaccharide content in the extract should reach a certain amount, and ...
